My thought is distributor which is driven off the other end of the cam shaft, not the crank.
The belt, being rubber, would seem to be an isolator of such force coming from the crank assy, ya know, shredding teh center out of the cam gear?
If something locked up the crank in the combustion chamber, it would more likely do more damage to a valve stem, rocker arm, piston, hell rod bent etc.. so im stumped. So always leave room for factor X , lol... like a bolt or tool left under the valve cover that finally wandered over:nervous: Maybe the cam gear was way over torqued or had the key jammed behind it or missing al together and the gear was bent and wobbly the whole time before it disintegrated :dunno: but.. what your theory paints in the quote makes no sense at all to me, im sorry.
